Dear Modalai Team,
Recent versions of voxl-vision-hub include a new and potentially very valuable off-board mode called WPS. 
The code (offboard_wps.c) is available at the GitLab, but has almost zero comments or instructions on how to use this offboard mode template.
A CSV file is mentioned to define waypoints (/tmp/voxl-mapper-traj_waypoints.csv)  but the file is nowhere to be found, neither in the drone side nor on the Gitlab files.
The online documentation for voxl-vision-hub does not even mention the WPS mode at all.
Could you please send more information and explain the use of WPS offboard mode ?
At this point we developers have very limited options as starting points for using voxl-vision-hub.  More information on how to use WPS would be very valuable.
Thanks.
